The new version of Internet Explorer in Longhorn 4051 is version 6.05.4051.0. Even though Longhorn is many years away (if ever!) the folks at Microsoft have realized that people want more from their browser, due to popularity of the competition, ex. Mozilla. UPDATE: Longhorn 4051 review.

Though I don't give props to IE, I certainly don't to Mozilla either. Whatever advantages Mozilla hs over IE is made null and void by its speed, or lack thereof. (Firebird is a different story though.)

To be fair, Mozila was always meant to be a development platform, rather than an end-user product (which is what netscape, firebird, galeon, epiphany and so on are).
